What a boundary actually is
A boundary is a rule you hold for yourself about what you will do, given what someone else does. It is not a rule for the other person. "You must stop calling me after 9pm" is a request. "If you call me after 9pm I will not pick up" is a boundary. The distinction matters because requests can be refused; boundaries are within the client's own control, which is precisely what makes them sustainable.
Almost every "boundary problem" in clinical work is one of three things: (1) a request being mislabelled as a boundary, (2) a boundary being stated but not enforced, or (3) a boundary that costs more to hold than the relationship can absorb. Naming which one is happening is the intervention.
The 6 types of boundaries, with examples
| Type | What it protects | Example |
|---|---|---|
| Physical | Body, personal space, touch. | "I'd rather not hug — handshakes are great." |
| Emotional | Capacity, emotional labour. | "I can't be your sounding board for this; I'm tapped out. Can we talk about something lighter?" |
| Time | Availability, calendar. | "I don't take work calls after 6pm. I'll respond first thing tomorrow." |
| Mental | Beliefs, opinions, values. | "I'm not going to debate this. We see it differently and that's okay." |
| Material | Money, possessions, home. | "I'm not lending money anymore. I love you and that's a hard line." |
| Digital | Screens, devices, online access. | "No phones at dinner. If something is urgent, you can step away to handle it." |
Setting a boundary: the script
A workable boundary has three components — state it, name the consequence, hold it. All three are required.
- State the rule, present tense, first-person. "I don't take calls after 9pm." Not "You shouldn't call after 9pm."
- Name the consequence — what you will do if the line is crossed. "If you call after 9pm I'll let it go to voicemail and call you back the next day."
- Hold the consequence the first time it is tested. The first test is the entire boundary. If you state the rule and then pick up the 10pm call "just this once," you have just taught the other person the rule does not apply.
How to use the worksheet
Most boundary work in therapy is rehearsal. The worksheet (linked below) takes the client through: (1) which type of boundary, (2) what specifically you will do, (3) what you will do if it's not respected, (4) the exact sentence you will say, (5) who you can tell so you have accountability, and (6) what feelings will show up when you hold it (usually guilt — that's expected and not a sign the boundary is wrong).
Do the worksheet in session for the first one. Boundaries chronically violated in childhood are not skill problems — they are activated trauma responses. Expect dysregulation; pair the work with a grounding skill the client can use immediately after the conversation.
When the boundary doesn't hold
- The other person escalates. Expected. The first time a held boundary changes the dynamic, the system pushes back hard. Coach the client: do not over-explain, do not re-litigate, repeat the boundary once, then disengage.
- Guilt floods. Almost always shows up. Treat guilt as a signal that an old rule is being broken, not as evidence that the new rule is wrong.
- The relationship can't hold it. Some boundaries reveal that the relationship was running on the absence of one. That is information, not failure.

Frequently asked questions
What are the 6 types of boundaries?+
Physical, emotional, time, mental, material, and digital. Some authors split or combine these (sexual boundaries are sometimes broken out from physical; spiritual boundaries from mental). The six above are the working set most therapists use because they map cleanly onto the conversations that come up in session.
What's the difference between a boundary and a request?+
A request asks the other person to change their behaviour. A boundary states what you will do given their behaviour. "Please don't yell at me" is a request. "If you yell at me I will leave the room and we can talk later when we're both calm" is a boundary. Requests are valuable but they can be refused; boundaries are within your control, which is what makes them sustainable.
Is there a free boundaries worksheet I can print?+
Yes — the printable linked above is one page, six prompts, designed to be filled out by hand before the conversation. Use it as homework after the in-session draft.
Why do I feel guilty for setting a boundary?+
Guilt almost always shows up when a long-standing relational rule is broken — even when the new rule is healthier. Treat the guilt as a signal that something old is changing, not as evidence the boundary is wrong. Plan a regulation skill (grounding, paced breathing, a short walk) for the 30 minutes after the conversation.
